Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552658, here are decompositions:

19 + 31552639 = 31552658
37 + 31552621 = 31552658
79 + 31552579 = 31552658
229 + 31552429 = 31552658
271 + 31552387 = 31552658
307 + 31552351 = 31552658
349 + 31552309 = 31552658
421 + 31552237 = 31552658

Showing the first eight; more decompositions exist.
